Improving path summary storage efficiency in smart contract symbolic execution requires algorithmic and structural optimizations. Implement delta encoding to store only differences between similar execution paths, reducing storage by 50-70%. Use Merkle Patricia Tries for path indexing, enabling O(log n) retrieval complexity. Apply lossless compression algorithms like Zstandard to path summaries, achieving 3-5x size reduction. Introduce hierarchical summarization where common prefixes are abstracted into shared nodes. Leverage sparse matrix representations for constraint systems, cutting memory usage by 40%. Store frequently accessed paths in on-chain caching layers with eviction policies based on last-access timestamps.
